Comparing the Evolution of Crystalline Silicon Photovoltaic Cells: Technological Route and National Specialization

Abstract There are at least three types of photovoltaic cells derived from raw materials, which have not been differentiated in most of the previous literature. From a global perspective, we focus on a mainstream product in the photovoltaic energy market: crystalline silicon photovoltaic cells (CSiPVCs). This paper delineates the technological developing trend and global geographical distribution of CSiPVCs. Furthermore, the specific technological evolution route is emphasized on a national level. In terms of policy implication in China, and particularly in the context of China's recent predicament in the international PV market, the paper establishes a framework to disclose, in depth, the gap between China and technologically advantageous nations. Policy suggestions for China are proposed as well.
